Calculate the volume, in ml, of a solution that has a concentration of 2.5 x 10-2M HCL when 0.100 moles HCL(aq).

volume=0.4ml

Explanation:

use the equation

n=c×v. first make v become the subject of the formula by dividing c on both sides of the equation

v=n/c

v=0.100÷2.5×10^-2

v=4×10^-4

v=0.0004L

now convert 0.0004L to ml by multiplying 0.0004 with 1000 to get 0.4ml

therefore the volume in ml is 0.4ml

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
